' RoAo-SCRAPER.

SPECIFICATION forming part of Letters Patent N o. 448,412, dated March 17, 1891. Application filed October S0, 1890. Serial No. 369,802. (No model.)

To all who-m, it may chimera.-

Be it known that I, WILLIAM H. CRITTEN- DEN, a citizen of the United States, residing at Beldenin the county of Lorain and State of Ohio, have invented a new and useful Road-Scraping Machine, of which the following is a specification.

My invention relates to that class of roadscrapers which will clean out the ditch beside the road and throw the dirt in toward the center thereof, and at the same time level it. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure lis a plan view. Fig. 2 is a side elevation. Figs. 3, 4, 5, 6, 7, 8, 9, and l0 are detached views of the several details. Fig. ll is a detailed sectional View showing the method of constructing the scraper and securing the parts together.

Sim ilarletters referto similar parts throughout the several views.

In the drawings, A represents the scraper', which consists of a plank about two feet in width and about eight feet in length, which is placed diagonally across the line of draft, as seen in Fig. l, the upper edge inclining somewhat to the rear, as seen in Fig. 2, and

is held firmly in position by studs B. To the lower front edgeof this plank is secured a cast-iron strip u, formed as seen in Figs. 3 and 9. To and over this strip and over the entire front surface of plank A is secured a strip of Sheet-steel a', vhich is curved to fit, and its lower edge forms, the cutting-edge of the scraper.

C represents an adjustable landside, having a point c curved inward (see Figs. l and 10) to assist in overcoming the side draft. Said landsideextends back about eighteen inches, and is secured in position so as to render it adjustable vertically, giving more' or less dip to the point, as desired,thus adapting it to the conditions of the soil where used. Said landside is seeuredin position by means of pin d', which fits through slot tu, and is provided with a countersunk head, which holds the plate firmly in positiornbut admits of it working freely in a vertical direction over the slot. At the rear end of the landside a lever d is strongly pivoted at its lower end to the framework of the scraper, and also to the landside just above, as seen in Fig. 9. l/Vhen the lever CZ is forced forward, the point is forced forward and downward as much as is desired. The reverse movement returns the landside to a level with the under surface of t-he scraper. At the opposite end of the scraper a supplementary scraper J is attached, which extends at nearly a right angle thereto, for the purpose of holding the accumulated dirt and carrying it forward to a point where it may be advantageously deposited. This attachment may be removed when desired. Said supplemental scraper J Vis firmly secured to the main scraper by means of a wrist-pin r, which extends through the rear end of the supplemental scraper and receives a key S. Said scraper J is held in place by stops t, which keep it from turning on pin r. The outer end is prevented `from swagging back by means of a rod` u, which connects it with the pole O.

The curved steel plate which forms the shear or cuttingedge of the scraper is strengthened and supported by means of the cast-iron strip a, to which it is secured, thus making it practicable to use very much thinner steel plate than has been used, saving considerable in weight of material and eX- pense of construction.

O represents a pole or tongue, which is at the rear secured to center stud B and cX- tends forward and is secured to and is supported by the axle of a suitable truck, by which itis drawn. Braces D D extend diagonally forward from the outside studs B B, and at their-forward end are secured to pole C. Brace E and iron braces ff extend also from the pole to the scraper for the purpose of giving strength and rigidity to the apparatus.

To the rear of the center of the scraper is hinged aA platform F, on which the operator may stand. (See Figs. l, 2, 5, 'and 6.) At the rear of platform F and directly under it is a lining-wheel G, which is secured in suitable bearings to lever I-I. Said lever is pivoted to the under side of the platform, as seen at g, Figs. 2 and 6. Lever II extends forward to near the front edge of the platform, where its end locks into a segment lz, which is provided IOO with a journal that extends upward through the platform, where it may be oscillatedby means of lever i, which is pivoted to the upper side of the platform and engages said segment, as seen in Figs. 2 and 5. By means of thisdevice the lining-Wheel may be def flected from the line of draftcto the right or left, as desired, and thus very materially assisting in controlling the direction of theapparatus, and by a skillful operator may be easily made to wholly overcome the powerful tendency to side draft. This result is greatly facilitated by the curved point of the landside, without which it would be impossible to accomplish the object, as any divergence from the line of draft tothe right would induce a corresponding divergence to the left of the forward end.

Vheels I I are secured in position by means of a system of compound levers, by whichthe scraper, platform, and lining-wheel. are ele- Vated at one or both ends from ,the ground for the purpose of turning around or transportation. The journals of wheelsII are se,

cured in suitable bearings lformed in bent lef ends of said, levers are connected to clutchlevers m by means of rodsl. Said clutch-levers are also pivoted at their lower ends to the edges of the platform F, and are provided with the ordinary clutch, which takes hold of and is held rigidly in position by semicircular Y racks. By a judicious management of these levers the scraper may be easily raised or lowered at either end to meet the requirements of the grade and distribute the dirt as desired.

What I claim as new, and desire to secure by. Letters Patent, is-
